CodeSandbox is a proprietary, browser-based platform for spinning up full-stack development environments and sharing live prototypes without local setup. It's convenient for quick demos and onboarding, but projects and compute run on CodeSandbox's hosted infrastructure under its own pricing.
Daytona is an open-source alternative for teams that want fast, isolated sandboxes they can self-host rather than rely on a third-party cloud IDE.
